How to choose
Start by counting how many things you need to record at the same time, then add one. That number decides the size of interface you need far more than the brand does.
Beginner
If this is your first interface, a two-input USB model is the right size. The Arturia MiniFuse 2, the smaller Focusrite units and the entry PreSonus models all give you two combined microphone and instrument inputs, phantom power for condenser microphones and a headphone output. Check that the interface works with your computer's connection, since many new models are USB-C, and make sure it has direct monitoring so you can hear yourself without delay. You do not need more inputs than that to learn recording properly.
Intermediate
If you have outgrown two inputs, decide whether you need more microphone channels or better sound from the ones you have. For more channels, four to eight input models from Focusrite, Audient, PreSonus and MOTU let you record a drum kit or a small band, and units such as the Arturia AudioFuse range add extra outputs for separate monitor mixes. For better sound, look at the preamp quality and the converters in models from Audient and Solid State Logic, and compare them with the same microphone in the shop.
Expert
At a professional level, the choice is about routing, expansion and consistency. MOTU interfaces are known for large routing matrices and many outputs, Universal Audio units add real-time processing on the way in, and Apogee focuses on converter quality in a compact form. Check whether the interface supports ADAT or other digital expansion, such as the Arturia AudioFuse X8 IN, so a studio can grow without replacing the core unit. Driver stability with your specific recording software matters as much as the specifications.

About audio interfaces
Every interface does the same basic job. It turns the signal from a microphone or instrument into digital audio your computer can record, and it turns the computer's output back into sound for your headphones and monitors. The differences are in how many inputs you get, how quiet and detailed the preamps are, how low the delay is while you play, and what else is built in.
Small desktop interfaces with two inputs cover most home recording: a vocal and a guitar, or a stereo keyboard. Larger units add more microphone inputs for drums and bands, extra outputs for separate headphone mixes, and digital connections so you can add more inputs later.
